It's very easy to make from a strip of denim cut from the leg of an old pair of jeans ( mine kindly donated by my brother )

Everything is hand sewn with invisible thread. From my stash I cut a piece of knitting lace in half and added a piece top and bottom, then a piece of the check ribbon. Next I gathered a piece of sheer ribbon and attached it down the middle. Then I fussy cut some of the butterflies out adding two together and attaching then on top of the gathered ribbon. Finished off with two rows of pearls and two hooks and eyes to fasten the cuff.
